Schlumbergera is a small genus of cacti with six to nine species found in the coastal mountains of south-eastern Brazil. These plants grow on trees or rocks in habitats that are generally shady with high humidity, and can be quite different in appearance from their desert-dwelling cousins. Most species of Schlumbergera have stems which resemble leaf-like pads joined one to the other and flowers which appear from areoles at the joints and tips of the stems. Two species have cylindrical stems more similar to other cacti.

To grow a healthy Christmas cactus, provide bright, indirect light, use a well-draining potting mix, and water only when the top inch of soil is dry to prevent root rot. These tropical, not desert, plants need higher humidity and cooler night temperatures (around 55-65°F) in the fall to set flower buds. Fertilize regularly during the growing season (spring to early fall) and stop fertilizing when buds appear.

Common Christmas cactus problems include root rot from overwatering, bud drop due to inconsistent temperatures or lack of darkness, and wilting or drooping stems from too much or too little water. Other issues can be too much direct light causing reddish leaves, or salt buildup from overwatering and improper drainage.
